Bacterial stem blight caused by Pseudomonas syringae pv. syringae is a common disease of alfalfa (Medicago sativa L). Little is known about host-pathogen interactions and host defense mechanisms. Here, individual resistant and susceptible plants were selected from cultivars Maverick and ZG9830 and used for transcript profiling at 24 and 72 hours after inoculation (hai) with the isolate PssALF3....
In tobacco and other Solanaceae species, the tobacco N gene confers resistance to tobacco mosaic virus (TMV), and leads to induction of standard defense and resistance responses. Here, we report the use of N-transgenic tomato to identify a fast-neutron mutant, sun1-1 (suppressor of N), that is defective in N-mediated resistance. Induction of salicylic acid (SA) and expression of pathogenesis-re...
Biotic stress related damage in plants could be managed by building disease resistance in cultivated genepool through breeding for plant resistance genes (R-genes). Recent studies show that R-genes conferring resistance to diverse pathogens in different plant species share a number of common functional motifs and are frequently clustered in the genome. This considerable conservation at the DNA ...
Molecular breeding incorporates efficient tools to increase rust resistance in five-needle pines. Susceptibility of native five-needle pines to white pine blister rust (WPBR), caused by the non-native invasive fungus Cronartium ribicola (J.C. Fisch.), has significantly reduced wild populations of these conifers in North America. Major resistance (R) genes against specific avirulent pathotypes h...
Longan (Dimocarpus longan Lour.), an important subtropical fruit in the family Sapindaceae, is grown in more than 10 countries. Longan is an edible drupe fruit and a source of traditional medicine with polyphenol-rich traits. Tree size, alternate bearing, and witches' broom disease still pose serious problems. To gain insights into the genomic basis of longan traits, a draft genome sequence was...
Abstract Alfalfa expresses significantly distinct sets of genes in response to infection with different rhizobial strains at the below species level (i.e., biotype or strain). However, differences transcriptomic profiles two alfalfa cultivars nodulated by a single rhizobium strain have been largely unexamined. In this study, comparative RNA-seq analysis cultivars, Medicago sativa cv. Gannong No...
Plant immunity to coevolved pathogens relies on the perception of pathogenic effectors by nucleotide-binding domain and leucine-rich repeat-containing (NLR) proteins-sophisticated intracellular receptors that have both perception and signaling roles in activating defenses. Given the conserved domain architecture of NLRs, a structural biology perspective is particularly relevant to understanding...
